DESCRIPTION OF VARIOUS ASPECTS

The following description the present teachings is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.
With general reference to the drawings, a shelving system constructed in accordance with the present teachings is illustrated and generally identified at reference character 10. In one application, the shelving system 10 is for a refrigerator. It will become apparent, however, that the present teachings may be used for other applications.
The shelving arrangement 10 of the present teachings may generally include a shelf 12 and a retention system or arrangement 14. As will be appreciated below, the retention system 14 may be operative to retain items on the shelf 12. In one particular application, the retention system 14 may serve to retain food and other items on a shelf 12 of a vehicle refrigerator in response to movement of the vehicle. The retention system 14 retains the items on the shelf 12 by establishing a barrier which prevents the items from forwardly moving off the shelf. Lateral movement of the items from the shelf 12 may be prevented by the refrigerator sidewalls, for example.
The shelf may be a solid shelf 12 constructed of glass, acrylic, plastic or other suitable materials. In alternative applications, the shelf may be a wire shelf. The shelf 12 may further include a first trim piece 19 and a second trim piece 21. The first and second trim pieces 19 and 21 may be constructed of plastic. The first and second trim pieces may define channels for receiving edges of the shelf 12.
The shelf 12 may be supported by a support arrangement 18. The support arrangement 18 may include a pair of arms 20 that selectively engage uprights 22 and a pair of transverse members 24 extending between the arms 20. The transverse members 24 may be received within channels defined by the trim pieces 19 and 21.
The retention system 14 may generally include a retainer member 26 and at least one connector member 28 for coupling the retainer member to the shelf 12. As shown in the drawings, the at least one connector member may include first and second connector members 28. The first and second connector members 28 may be substantially identical to one another. The connector members 28 may be formed of plastic or other suitable material.
The retainer member 26 may include a central portion 29 that substantially extends between first and second lateral sides 30 and 32 of the shelf 12. The central portion 29 may extend across the shelf 12 in a substantially linear manner. The retainer member 26 may additionally include first and second end portions 34 and 36. The first and second end portions 34 and 36 may be substantially identical and may include upper portions that depend from the central portion 29. These upper portions may extend rearwardly from the central portion 29 when the retainer member 26 is in a deployed position (as shown in solid lines in FIG. 1, for example). Intermediate portions of the first and second end portions 34 and 36 downwardly extend to hooked-shaped lower portions. The retainer member 26 may be unitarily formed of metal rod stock. Alternatively, the retainer member 26 may be formed of plastic.
The connector members 28 couple the retainer member 26 to the shelf 12. Prior to addressing the construction and function of the connector members 28, an understanding of the resulting movement allowed by the connector members 28 between the shelf 12 and the retainer member 26 is warranted. The retainer member 26 may be rotatably moved between a deployed position (shown in FIG. 1 is solid lines) and a stowed position (shown in FIG. 2). The retainer member 26 may also be upwardly translated from the deployed position to an intermediate position (shown in FIG. 1 in dashed lines). The retainer member 26 may be secured relative to the shelf 12 at various positions along the length of the first and second lateral sides 30 and 32.
Each of the connector members 28 include a first side (shown in the perspective view of FIG. 4) that faces the shelf and an opposite second side (shown in the perspective view of FIG. 5). The connector members 28 may additionally include a top portion and a bottom portion. At the top portion, the first side of the connector member 28 may define a channel 40. In this regard, the top portion may include a pair of spaced flanges to define the channel 40. The channel 40 may slidably receive a side of the shelf 12.
The lower portion of the connector member 28 may include a wall 42 with a bottom portion that is curved such that the wall defines a generally U-shaped channel 44. As will be discussed below, the U-shaped channel 44 receives the lower portion of one of the ends 34 and 36 of the retainer member 26. The lower portion may further include a stop member 46. The stop member 46 may be connected to the wall 42 through a horizontally extending web 48.
At the second side, the top of the connector member 28 defines an opening 48. The opening 48 leads to the channel 44. A pin 50 may be integrally formed with the upper portion and may extend into the opening 48.
The lower hook portions of the first and second ends 34 and 36 of the retainer member 26 pass through the openings 48 of the respective connector members 28. After the connector members 28 are selectively positioned along the lateral sides 30 and 32 of the shelf 12 to in desired positions, the retainer member 26 is downwardly translated to the deployed position (shown in solid lines in FIG. 1). In this position, the hook portions of the first and second ends 34 and 36 are seated in the channels 44 of the respective connector members 28. Rotation of the retainer member 26 is precluded through contact between the lower hook portions and the wall 42.
When the lower hook portions are seated in their respective connector member channels 44, the stop portions 46 are urged by the lower hook portions against an inherent spring bias and into contact with the shelf 12. Through friction, this contact may prevent sliding movement between the connector member 28 and the shelf 12 and thereby fix the position of the retainer member 26 relative to the shelf 12. In certain applications, it may be desirable to provide the stop portions 46 with cooperating structure to further preclude movement relative to the shelf 12. For example, cooperating teeth may be carried by the stop portion 46 and the shelf 12.
When the retainer member 26 is translated upwardly (in the direction indicated by Arrow X in FIG. 1), the lower hook portion of each end 34 and 36 is displaced from the U-shaped channel 44. This upward translation is limited by engagement of the respective pins 50 with the lower hook portions. The retainer member 26 may now be rotated about an Axis Y (see FIG. 1) that passes generally through the pins 50 to the stowed position (see FIG. 2). The retainer member 26 may also be translated in the direction of Arrow Z (see FIG. 1) along the shelf 12 as the stop portions 46 are no longer pressed against the shelf 12 by the lower hook portions. Through this translation in the direction of Arrow Z, the position of the retainer member 26 may be adjusted depending on the amount of items present on the shelf 12. In this manner, the items on the shelf may be effectively captures between the retainer member 26 and the refrigerator sidewalls.
It will now be appreciated that a refrigerator shelving system 10 is provided that provides a retainer member 26 which can be employed at various points along a shelf 12. Additionally, the present teachings provide a retainer system 14 that may be utilized with a solid shelf 12.
The description of the invention is merely exemplary in nature and, thus, variations that do not depart from the gist of the invention are intended to be within the scope of the invention. Such variations are not to be regarded as a departure from the spirit and scope of the invention.
